If you were buying nuts, would you rather pay $9/kg or $4/500g?
ignore the last reply, but look at this posting

So it would be $4/500g because $4/1/2kg * 2/2= $8/1kg.
$8<$9
correct again.
To determine which option is better when buying nuts, you need to compare the prices per unit weight.
Option 1: $9/kg
Option 2: $4/500g
To make the comparison easier, convert the units so that they are the same. Since there are 1000 grams in a kilogram, you can convert the price of option 1 to price per 500g by dividing $9/kg by 2:
Option 1: $9/kg = $4.50/500g
Now you can directly compare the prices:
Option 1: $4.50/500g
Option 2: $4/500g
In this case, Option 2 has a lower price per 500g, making it the cheaper option. Therefore, if you were buying nuts, it would be more cost-effective to choose Option 2 priced at $4/500g.
